Updates from Jean-Fracois for the TDA998x driver, which are on top of
the fixes you have previously pulled, except these changes aren't
intended for -rc, but the next merge window.

Several of these are issues of correctness - passing more correct HDMI
info packets, not reading registers in older chips documented as write
only (despite appearing to be read/write in later chips).  Others are
code cleanups (using definitions rather than constants where we have
them already in the kernel).

Additional functionality is also added by way of optional support for
the IRQ from the TDA998x, which allows us to avoid busy-waiting for
the EDID reads.

drm: DisplayPort AUX framework for v3.15-rc1

This series of patches implements a small framework that abstracts away
some of the functionality that the DisplayPort AUX channel provides. It
comes with a set of generic helpers that use the driver implementations
to reduce code duplication.

* tag 'drm/dp-aux-for-3.15-rc1' of git://anongit.freedesktop.org/tegra/linux:
  drm/dp: Allow registering AUX channels as I2C busses
  drm/dp: Add DisplayPort link helpers
  drm/dp: Add drm_dp_dpcd_read_link_status()
  drm/dp: Add AUX channel infrastructure

Implements an I2C-over-AUX I2C adapter on top of the generic drm_dp_aux
infrastructure. It extracts the retry logic from existing drivers, which
should help in porting those drivers to this new helper.

- sleep for 1-2 ms after setting local sink to D0 state
- read and write consecutive registers where possible
- read DPCD revision when link is probed
- remove duplicate kerneldoc

The function reads the link status (6 bytes starting at offset 0x202)
from the DPCD so that it can be conveniently passed to other DPCD
helpers.

This is a superset of the current i2c_dp_aux bus functionality and can
be used to transfer native AUX in addition to I2C-over-AUX messages.

Helpers are provided to read and write the DPCD, either blockwise or
byte-wise. Many of the existing helpers for DisplayPort take a copy of a
portion of the DPCD and operate on that, without a way to write data
back to the DPCD (e.g. for configuration of the link).

Subsequent patches will build upon this infrastructure to provide common
functionality in a generic way.

the IA32_PERF_CAPABILITIES MSR; the SDM specifies that we should check
CPUID[1].ECX[15] (aka, FEATURE_PDCM) instead.

This was found by KVM which implements v2+ but didn't provide the
capabilities MSR. Change the code to DTRT; KVM will also implement the
MSR and return 0.

When using BTS on Core i7-4*, I get the below kernel warning.

$ perf record -c 1 -e branches:u ls

Make intel_pmu_handle_irq() take the full exit path when returning early.

ENDPTFLUSH and ENDPTPRIME registers are set by software and clear
by hardware. There is a bit for each endpoint. When we are setting
a bit for an endpoint we should make sure we do not touch other
endpoint bit. There is a race condition if the hardware clear the
bit between the read and the write in hw_write.

The change (008fa749) that moved the
node release code to a separate function broke death notifications in
some cases. When it encountered a reference without a death
notification request, it would skip looking at the remaining
references, and therefore fail to send death notifications for them.

In deadline class we do not have group scheduling like in RT.

dl_nr_total is the same as dl_nr_running. So, one of them should
be removed.

A hot-removed CPU may have ID that is numerically larger than the number of
existing CPUs in the system (e.g. we can unplug CPU 4 from a system that
has CPUs 0, 1 and 4).

Thus the WARN_ONs should check whether the CPU in question is currently
present, not whether its ID value is less than num_present_cpus().
